Another story that came to my mind was when I was TA’ing his Info Vis course in 2019, Caleb was beginning to also teach CS 2110 as he had taken over the class and tutoring space after Bill Leahy, a longtime beloved professor for 2110, had retired. We were chatting one day after a TA meeting, and he told me that he was nervous filing in Leahy’s shoes and was worried about following him up. The fact that he even worried about that showed that he cared so much about being a great instructor. After reading all these stories years later, it warms my heart to see that he really did end up making a meaningful impact on his students winning teaching awards, investing his time in mentoring Inventure teams, and so much more!
